Figure 2From: Genomic divergence between nine- and three-spined sticklebacksDistribution of pairwise K a and K s distances between nine-spined stickleback unigenes and their three-spined stickleback orthologs. Genes with K a /K s ratio >1 fall above the black line while those with K a /K s ratio between 0.5 and 1 fall between the gray and black lines.Back to article page
